Supported Protocols

Legislated OBD-II protocols:

  • ISO15765-4 (CAN)
  • ISO14230-4 (Keyword Protocol 2000)
  • ISO9141-2 (Asian, European, Chrysler vehicles)
  • J1850 VPW (GM vehicles)
  • J1850 PWM (Ford vehicles)
  • Single-Wire CAN (SW-CAN)
  • Medium-Speed CAN (MS-CAN)

Supported Devices

OBDLink MX Wi-Fi can work with any Wi-Fi-enabled smart phone, tablet, or PC. Officially supported platforms (this means, we verified that MX Wi-Fi works with apps running under these operating systems) include:

  • iOS (iPhone, iPad & iPod Touch)
  • Android phones & tablets
  • Windows Phone
  • Windows 2000 and later PCs

Given MX’s open architecture and strict adherence to the 802.11 standard, we anticipate apps to be developed for other platforms as well. In fact, compatible third party applications are already popping up for several other platforms, including Blackberry and Linux.

You’ll have lots of app and software options, as OBDLink MX is backwards-compatible with the popular ELM327 command set. Here’s a small sample of apps and software we recommend:

iOS:

Android:

Windows:
